Recently we posted our new germination process we recommend which weakens the hard seed coat of the lucerne tree seeds to encourage germination. This new scarification process has 2 simple steps –
- Nick (cut or snip off) the edge of the seed with a clipper or sharp blade and then
- Soak the seeds in hot tap water (not boiling water) overnight
We have been doing several trials to test this process and below are the photos to show how effective it is when one nicks or snips off the top edge of the hard seed coat.
Within 1 hour, the nicked seeds were already swelling and by the next morning all the seeds were swollen and ready for planting. Compared to the control batch of seeds simply soaked in hot tap water.
A few seeds in the uncut control batch did swell, but when I took those out, I saw that 2 had broken seed coats and the other 2 were some of the nicked seeds that fell back into my seed container as I worked.
Please use both scarification methods when you want to germinate your seeds for optimum seed germination.
Life is in the seed!
